Log Fill

In the process of sawing logs a sawyer must determine where he must make the first cut on the log in order to come out with the desired final piece or "CANT". In most cases this require a great deal of mental calculation, and years of practice to be proficient. The inability to quickly calculate this starting point forces the sawyer to start sawing at the bark line and then forcing him to saw a useless shim off of the "cant" in the middle. Having to do this not only wastes the time it takes to make the extra cut, it also wastes wood. If the log had been slabbed heavier (the thickness of the shim) the first board could be edged wider yielding more usable lumber. The G401 can eliminate this common problem. By the simple press of a button the computer will tell the operator how many of the selected boards are in the log down to the desired size "cant", and can line the saw up with the first piece. This process can be done with many different sized "boards", "cants", and even mixed lumber sizes.

Automatic Coast Adjustment

All saw positioning systems have coast. Coast is the distance traveled after system has cut off or de-energized. Conventional sawmill setworks typically rely on a Cam/Limit Switch configuration (or a similar method) that move the saw or log in a certain distance but have no way to check or compensate for coast changes due to log weight, mechanical wear, fluid temperature, and other factors. The G401 has automatic coast adjustment that will detect and adjust for coast changes.

Dog Limit & Tapered Cant Protection

A costly mistake often made, especially by new sawyers, is sawing into the "dogs" or log clamps. This almost always ruins the blade or band and generally takes much time to recover from. If the "dogs" are electrically operated the G401 can detect them and disable the set if it will put the saw beyond the "dogs out limit" that was entered during the machine setup. Another common mistake made is forgetting to turn off the log tapers and sawing a wedged shape "cant". If an electrical signal is connected to the the log tapers input on the G401 the computer will disable certain features while the log tapers are on.
